PROBLEM TO BE SOLVED: To obtain a negative capacitor circuit that does not satisfy an unneeded oscillation condition by reducing loop gain in the negative capacitor circuit. SOLUTION: An attenuator 4a is inserted and connected serially between the gate terminal of a first FET 1a and the drain terminal of a second FET 1b of the two FETS whose sources are grounded, an attenuator 4b is inserted and connected serially between the drain terminal of the first FET 1a and the gate terminal of the second FET 1b, an inductor one end of which is grounded is connected to the drain terminal of the first FET 1a, and a load one end of which is grounded is connected to the drain terminal of the second FET 1b.
